Recently, it has been observed that few drops of water on the surface of oxide materials can generate electricity which is eco-friendly and cost effective. This hydroelectric cell (HEC) may serve as an unconventional source of electrical energy. HEC production cast is very low. Porous SnO₂ samples for hydroelectric cell have been prepared by solid-state sintering method. Phase formation and structural analysis of the sample was confirmed by X-ray diffraction pattern using Rietveld analysis. The surface morphology of the sample was determined using field emission scanning electron microscopy. Average grain size of porous sample was depicted 65 nm using image j software. The pore size distribution and specific surface area of SnO₂ nanoparticles were examined by the Barrett–Joyner–Halenda technique. A circular pellet having diameter of 2 inch and a square pellet having a side of 2 cm was prepared to study the hydroelectric properties. Peak current value 72.1 mA was observed in circular pellet with almost constant voltage of 0.981 V whereas peak current and voltage values for the square pellet were 12.5 mA and 0.972 V respectively. Dissociation of water and conduction phenomenon have been confirmed using dielectric and DC conductivity behavior of samples.

近来，已经观察到氧化物材料表面上的几滴水可以产生电力，这是生态友好的并且具有成本效益。该水力电池（HEC）可以用作非常规的电能来源。HEC的生产量非常低。通过固态烧结法制备了水力电池用多孔SnO ₂样品。使用Rietveld分析通过X射线衍射图确认样品的相形成和结构分析。使用场发射扫描电子显微镜确定样品的表面形态。使用image j软件将多孔样品的平均晶粒尺寸描绘为65 nm。SnO ₂的孔径分布和比表面积纳米粒子通过Barrett-Joyner-Halenda技术进行了检查。制备具有2英寸直径的圆形粒料和具有2cm边的正方形粒料以研究水电性质。在几乎恒定电压0.981 V的圆形颗粒中观察到峰值电流值为72.1 mA，而方形颗粒的峰值电流和电压值分别为12.5 mA和0.972V。使用样品的介电和直流电导率行为已经证实了水的离解和传导现象。
